(Jay Allen Sanford tunes into San Diego music on the public airwaves.)
One of the many things we can either thank or curse the U.S. Congress for is public-access television. In the 1970s, as TV cable companies were growing into regional monopolies, Congress mandated that larger cable providers must put aside channels for public-produced community programming.
Today, there are over a thousand public access TV stations operating nationwide. When the city of San Diego grants charters to cable giants like Cox and Time-Warner, those companies guarantee this access to the airwaves, training (at no charge) interested community residents to run the equipment and to shoot and produce their own programs.
